Siemens software for digital industries and climate technology company sustain designed a way to add carbon emissions data to Siemens Xcelerator. Siemens created its Teamcenter Carbon Footprint Calculator software to help teams measure, simulate, reduce and track the carbon footprint of their products early in the development phase. The calculator uses sustamize’s product footprint engine, which has a pre-packaged CO2 library of emission factors. “Our collaboration with sustamize will enable customers to understand the environmental impacts of their products and processes early in product development based on comprehensive and up-to-date data,” said Eryn Devola, vice president of sustainability, Siemens Digital. Software Industries.

Ansys delivered a commercial Finite Element Analysis (FEA) solver that can accelerate structural mechanical models, such as for the automotive industry. The AWF supports AMD Instinct accelerators, new GPUs for data centers and supercomputers. Ansys says it has developed APDL code that interfaces with AMD ROCm libraries on Linux, which will support performance and scaling on AMD accelerators.

Infineon Technologies signed a multi-year supply agreement with the American company II-VI Incorporated to expand the semiconductor company’s supplier base for silicon carbide (SiC) wafers. SiC, a compound of silicon and carbon, is used in industrial applications but is also increasingly found in electric mobility. SiC power semiconductors are used in main inverters in electric vehicle powertrains, on-board battery charging units and charging infrastructure. II-VI and Infineon are also working on the transition to 200 mm diameter SiC wafers.

Researchers at United StatesMinistry of Energyit is Oak Ridge National Laboratory (ORNL) and the University of Tennessee, Knoxville, discovered a key material for fast-charging lithium-ion batteries in its search for a vehicle charge of 15 minutes or less. The material, a new compound of molybdenum-tungsten-niobate, or MWNO, could replace the graphite anodes used today. “Because of this slow lithium-ion movement, graphite anodes are seen as a barrier to extremely fast charging. We are looking for new low-cost materials that can outperform graphite,” said the ORNL researcher, Runming Tao, in a press release, “Our approach focuses on non-graphite materials, but these also have limitations. Some of the most promising materials – niobium-based oxides – have complicated synthesis methods that are not well suited to the industry.

Qualcomm says its pipeline of winning automotive designs – an estimated future size of award-winning automaker programs based on forecasts from automakers and Tier 1 suppliers, reached $30 billion as of September 22, 2022. The company has awarded a much of the rise to its Snapdragon Digital Chassis solutions.

The NHTSA estimates in an initial release of 2022 traffic data that 20,175 people died in motor vehicle traffic accidents in the United States so far this year, up 0.5% from the first half of 2021. The total death toll for 2021 in the United States was 42,915, up 10.5% from 2020.

The United States National Highway Safety Administration (NHTSA) ordered You’re here to recall certain Tesla models in which the power windows do not detect obstructions when closing. Windows are a hazard to anyone who has a limb in the way. Tesla plans to do an over-the-air (OTA) update to fix the issue.

Ubiquitous Computing

RISC-V Processor IP Company Codasip is now a member of the OpenHW Groupwhere Codasip will contribute to the RISC-V formal verification standards.

Flexible Logix will use Semifore, Inc.of CSRCompiler software on Flex Logix’s advanced inference chip design. Flex Logix manufactures eFPGAs and AI inference chips and modules. Its InferX X1 is an AI edge inference accelerator that can handle high volume applications. “These designs are very complex, and the hardware and software interfaces are critical to basic performance and functionality. Semifore’s CSRCompiler ensures that hardware and software interfaces work as expected, and that hardware and software teams can test the interaction during chip development,” said Charlie Roth, vice president of hardware R&D, Flex Logix , in a press release.

AMD unveiled the new line of Ryzen 7020 Series and Athlon 7020 Series processors for mobile phones.

Infineon introduces a single-stage flyback AC-DC controller IC for battery charging. The ICC80QSG single-stage PWM controller is used in flyback topologies in combination with Infineon’s CoolMOS P7 (SJ) superjunction MOSFET devices. Designers can manufacture battery chargers with scalable power designs up to 130W suitable for adapter, printer, PC, TV, monitor, set-top box, and audio amplifier applications.


Risks released its version 2022.2 of the True Code software tool, which helps software developers find and fix security vulnerabilities in embedded code. One of the updates extends fault injection attack simulations in True Code. Development teams can create test cases that can run automatically during the daily build process without needing the physical hardware the software is being developed for to find fault injection vulnerabilities early in development.
